Punctuality means a lot to English people, and they see that being on time is a courtesy. However, if one is running late for 10 minutes it is still acceptable. Do apologize and give your reasons. Formal meetings are expected to schedule with planning on timely manner.
Queuing and waiting for your turn are one social etiquette--- no one should push or jump any lines; always give way to the elderly and needed as a civilised manner.
Saying “sorry” is a sign of strength and mannerism, and so as “thank you”, “please”, and “excuse me”. Modest statements (and sometimes “understatements”) and gratitude are often used (such as “perhaps”, “possible”, and “could be”) as good social protocols.
Holding the door for the next person coming, and do not forget to take over from someone. Always offer to help those who need help even if they have not asked personally.
Do cover your mouth when you sneeze, cough, or yawn; do not spit or speak loudly in public. It is always polite to ask if someone follows your conversation.
Raise questions after a person finishes the conversation: it is often encouraged and expected to show. Do not interrupt when someone is talking to you, and always try to keep one arm’s length away not to appear too aggressive nor intrusive.
